loses/enter
RuBisCO, is an ____ involved in the first major step of _____ fixation, a process
by which atmospheric carbon dioxide is converted by plants to energy-rich
molecules such as ____ .
enzyme/carbon/glucose
aquatic plant leaves are very _____ so co2 can come in and not depend on its
_____
thin/stomata
T/F: co2 partial pressure is going up on land and water and so is dissolved
co2 ,which means atmospheric is going up too
True

in via openings known as ____.
CO2/stomata.
,The ___ ___ of stomata can expand to close the opening or shrink to increase the

T/F: the more co2 in plants, the better it will grow and better the nutrition
False: it will grow better but it will not always have better nutrtion. they will usually have
less zinc and iron
adding more of a ___ factor increases the rate furth until another factor becomes
